Hormone therapy in Japan?

Hi everyone :),

My friend and i are planning our year for Japan and already got our Working Holiday Visas approved.

Now a big question is, my friend is on hormone therapy (testosterone) and we've been looking at different clinics already, but it is difficult to find more information being still in Germany.

Has anyone here been through a similar situation? Do you have any experience with this or know of any clinics, resources, or contacts that could help? Any advice would be a huge help!

Thanks so much.
